3 Different Types of Contracts in Project Management

I’m a PMP trainer, and let me tell you, projects rely on the foundation established by various types of contracts in project management. Through observing numerous project management contracts, I discovered how contracts can lead to both deal success and failure. I eagerly want to share what I know about contract types in project management, especially for those enrolled in an Online PMP exam prep course.

These contracts possess independent characters, operating through fixed-price, cost-reimbursable, time, and material agreements. My analysis will simplify complex concepts of project contract types using real-world scenario examples from my 2025 training so you can easily pass your PMP certification or nail your upcoming project assessment.

When I began working as an instructor for project management contracts, I understood that these documents extend beyond dull paperwork. The contractual agreement functions as a business handshake, creating guidelines for all participants. A project management contract establishes all work requirements while defining costs and distributing accountability between parties. Project management becomes chaotic quickly due to the absence of a proper contract type in project management, leading to missed deadlines and budget disputes.

I recently read somewhere that more than 60 percent of project hiccups stem from poorly defined agreements, making it essential to understand the types of contracts in project management and their associated types of project risk.

Project management contracts function as essential documents that maintain a clear understanding between all the parties involved in the project, including stakeholders. Project management requires three main contract types of project management for execution, including fixed-price contracts, cost-reimbursable contracts, and time and material contracts. Let’s understand them all.

I use fixed-price contracts primarily when a project plan presents a clear picture, as outlined in my Techademy’s PMP course. Fixed prices are one of the types of contracts in project management that represent an agreement that specifies the initial payment amount, which remains unchanged even after project completion. I enjoy using my trainer role to demonstrate the project management contract format, which makes sellers accountable for meeting delivery requirements within prescribed costs.

What’s It About?

• The entire work rate remains fixed throughout.
• Whenever the project turns out badly, the seller pays all additional expenses.
• It’s one of the contract types in project management that operates with an exact project scope.
   

Real-Life Examples

The project management contract we made for $500,000 bound the contractor to maintain the price despite lumber price fluctuations. Another time, the student presented an instance where their organization applied a fixed-price project management contract that delivered a website redesign, receiving a flat payment of $30,000.

No matter how experienced your project team is, you need to be sure of the exact requirements before using fixed-cost contracts in project management. Construction projects commonly rely on this contract type in project management since it offers reliable forecasting capabilities, often supported by project estimation techniques.

Every burger purchase comes with a price known before taking the first bite.

The category of cost-reimbursable contracts stands apart from other types of contracts used in project management. Project management contracts under this arrangement enable sellers to charge their actual expenses and add profit on top. This contract type in project management serves well when you find it difficult to envision the project development process due to uncertainty, as detailed in a comprehensive project report.

What’s It About?

• When dealing with this contract type, buyers must pay for labor costs together with material expenses and the contract fee at either a flat rate or as a proportion.
• The flexibility of this contract establishes it as one of the most popular options for project management of research assignments.
• When costs exceed expectations, the buyer becomes responsible for additional financial loss.

Real-Life Examples

A few months ago, I coached a team on a contract in project management for a medical research project.

I remember coaching a team on a contract in project management for a medical research project. Due to uncertainty about testing requirements, the laboratory received $200,000 for both equipment and staff hours and added a 15% administrative fee. 

Another example is that the consulting company I advised used a cost-reimbursable project management contract to update the factory operations and incurred $150,000 in costs and a $20,000 success bonus fee.

About one-third of technological projects use this flexible type of contract in project management because it provides tolerance when project plans need adjustment. I consistently alert my students to monitor project costs because T&M contracts easily escalate in project management contexts.

In my experience, about a third of tech projects lean on this since it’s forgiving when plans shift. But I always warn students to keep an eye on those costs, or this contract type in project management can spiral.

The Time and Material (T&M) contract functions as the middle option among types of contracts in project management. T&M contracts derive value from the hours employees work and the materials they use, thus offering great flexibility. This project management contract type provides flexibility for short projects and provides adaptability in uncertain situations, which is critical when learning how to create a project plan.

What’s It About?

• You pay for time (like hourly wages) and materials (like software licenses).
• Projects are usually controlled through cost thresholds to prevent unlimited expense growth.
• This particular contract type in project management distributes risks between the participants. 

Real-Life Examples

I had a client who implemented a T&M contract in project management to fix his company’s network by paying technicians $80 each hour  for their work and materials used, with maximum expenses limited to $15,000

Another example: A student presented a project management contract for event setup, including decorator fees at $50 per hour and actual flower costs to maintain open-ended yet controlled costs.

This type of contract in project management is frequently used for IT and creative projects. I encounter it in about 20% of my work. I prefer contractual agreements for swift work tasks, yet I advise folks to track project hours to avoid excessive spending when using this contract type in project management, often visualized through network diagrams in project management.

Contract types in project management stand out in different ways from each other. Here’s how the types of contracts in project management stack up:

The selection of the right contract type in project management depends on the defined characteristics of each project. Here are the questions you should ask before choosing any type of contract in project management:

• What’s the Scope Like? When you have a solid plan, use the fixed-price project management contract. Select cost-reimbursable for developing an application with unclear specifications. Maintenance assignments work best with Time and Material contracts in project management.
• Who Can Handle Risk? When working with clients who have restricted budgets, stay away from cost-reimbursable contract types of project management. As sellers hate risk, they choose fixed-price contracts.
• How Long’s the Job? The duration of tasks affects the selection of contracts in project management. T&M contracts are best for shorter projects, and fixed-price contracts are for longer builds.
• What’s the Market Doing? Because prices are expected to shift in 2025, use caution when using fixed-price contract types in project management because suppliers tend to offer cheap goods or services at low-market prices.

Pro Tip: Analyze project details like detectives to identify appropriate contract types in project management. Research reveals that 55% of project managers select their project management contracts according to the clarity of scope definitions to prevent issues.

Every type of contract in project management creates challenges, yet I possess proven avoidance strategies based on my extensive experience teaching professionals in this field.

Fixed-Price Contracts

1. What Can Go Wrong?

• Sellers frequently attempt to cut costs, which affects the product quality.
• Changes made by the client will trigger conflicts about the project scope.
   

2. How I Fix It:

• Every element of the project management contract should receive a complete formal agreement before project initiation.
• A defined process for handling scope alterations needs to be included when using this contract type in project management.
• Regular work checks are conducted by doing weekly inspections to spot problems.

Cost-Reimbursable Contracts

1. What Can Go Wrong?

• The seller's carelessness will lead to an extreme increase in costs.
•  Clients become anxious when project budgets remain unclear.
   

2. How I Fix It:

• A project management contract must contain specific budget constraints to limit financial expenses.
• I track all expenditures by maintaining a proper spreadsheet for perfect control.
• Ask for the receipts to maintain honesty in contract-type project management.

Time and Material Contracts

1. What Can Go Wrong?

• Sellers frequently add extra hours to their time logs to increase payment amounts.
• Speed pressure cannot prolong work durations.

2. How I Fix It:

• Every project management contract requires a maximum expenditure amount as a crucial clause.
• Daily review of timesheets helps detect unnecessary additions in contract types and project management 
• Payments should be linked to defined mini-goals, allowing tasks to progress faster.

An organization can cut budget overruns by 15% through appropriate risk planning with contracts in project management. Adjustments must be made to the plan according to the specific type of contract in project management.
